the glass in the feeder bowl, we her with workers from the glass melting plant of the Severodonetsk pastic. factory of fiber glass reinforced plastics, developed and tested a new configuration of the bowl with a dis- persing spout. The presence of a spout enabled us to change the flow of glass, to almost completely elimi- nate "stagnant" glass and devitrifie of the glass in the front part of the bowl(Fig. 2). The tempera ture here was increased to 1160-1165C As a result of these studies and of the commercial trials, we improved the composition of the alkali glass and developed the technology for melting it and for making glass balls from it. The good results achieved in making fiber from glass No. 7A indicates a real possibility for considerably reducing the cost of reinforcing materials made from alkali glass LITERATURE CITED ociety of Plastics Industry, Proceedings of the 22nd Annual Technical Conference, Washington (1965) 2.
